Patent CA-2593721-A1 (CA)
Inventor: GEIER DAVID
IPC: H03F3/72
Filed: 2007-06-27
Abstract: A pulse step modulator employs a plurality of series connected unit step power amplifier modules. Each module is turned on by a turn-on signal t o provide a unit step voltage of a given value. An output circuit is connected to the modules for providing an output voltage to a load and wherein the output voltage is a multiple of the unit step voltages in dependence upon the number of modules that are turned on. The modules are sequentially turned on in a given order and are turned off in the reverse order. An encoder provides turn-on signals with each turn-on signal being applied to a selected one of the modules. The number of turn-on signal s provided varies as a function of the magnitude of a time varying input signa l. A controller alternately turns enables or disables (in a swapping manner) one of a pair of associated modules as the magnitude of the input signal increases and decreases.

Patent CA-2621781-A1 (CA)
Title: Deep water completions fracturing fluid compositions
Inventor: CREWS JAMES B
IPC: C09K8/70
Filed: 2006-09-06
Abstract: It has been discovered that fracturing fluid compositions can be designed for successful deep water completion fracturing fluid operations. These fluids must be pumped relatively long distances from offshore platforms to the reservoir, and they are often subjected to a wide temperature range. Under these conditions, it is necessary to inhibit the formation of gas hydrates in the fracturing fluid compositions, as well as to delay the crosslinking of the gels that are formed to increase the viscosity of the fluids prior to fracturing the formation. Preferably, two different gas hydrate inhibitors are used to ensure placement of a gas hydrate inhibitor in most parts of the operation. In addition, as with all offshore or deep water hydrocarbon recovery operations, it is important that the components of the fracturing fluid compositions be environmentally benign and biodegradable.

Abstract: For determining production-inherent mistuning of integrally manufactured rot or wheels (blisks) on the basis of the identification of blade natural frequencies, the individual blades are excited independently of each other and the vibratory response is measured for the calculation of the respective blade natural frequency and of mistuning. During measurement the blades not under investigation are additionally mistuned by temporarily applying an identical extra mass to eac h of them, such that coupling effects disturbing the measurement of the vibratory response of the excited blade are shifted away from the natural frequency-ne ar range of the blades and hence eliminated.
